ABSTRACT
Particles attached to thin foam films can both stabilize or destabilize the film hence, to understand the conditions under which stability is promoted, consideration must also be given to those conditions under which stability is actively reduced. Gaining new insight into the particle stabilized thin liquid film system will require new methods to simulate the particle-film interaction as well as an increase in the scale of the models. A useful method for investigating the fundamental behavior of the system is to reduce it to 2D and examine a single circular particle bridging both sides of the thin liquid film. Both surfactants and particles stabilize foams, but, arguably, they do so through different mechanisms and on different scales. Morris et al. investigated the effect of particle packing in 3D using the Surface Evolver program. As a higher capillary pressure is required to cause film failure, the thin liquid films have a longer lifetime, producing a more stable froth.
